The larvae produce erosion characteristics, initially they damage the leaves and later the fruits. In the leaves, the attack is at the bottom of the page, but the ribs and the top of the flap are saved. While in young pomace and sequoia fruits embroidery larvae only cause surface erosion, erosion extends to the peduncular cavity, rendering them inadmissible and easily susceptible to rotting processes. In the vine, the larvae destroy the flowers and damage the grapes, exposing them to botrytic attacks.

While the young fruits of pip fruit and of stone cause larvae embroidery only superficial erosions, from people near maturation erosions extend the cavity of the stem, incommerciabili and make them easily susceptible to rotting processes.

This tortricide works in our rooms for three generations a year. Winter as a chrysalis, protected under fallen leaves. The first adults appear at the end of March and the beginning of April and the blinking lasts approximately one month. About a week from the couple, the females lay the eggs in yellow ooplaces on top of the leaves. The first-generation larvae appear as early as May and grow at the expense of parenchyma of leaves and then of fruit juice. Once its development is complete, the larvae grow in a silk cocoon where the metamorphosis that will give rise to adults begins in the second half of June.

The fight against Eulia follows the methodologies of guided and integrated struggle; the monitoring is done with sexual traps.

The methodology is the following:

- Traps are placed in an orchard in mid-March;

- The number of sexual traps is one or two per company.
